MILKING-MACHINE.

Specification of Letters Patent.

Patented Sept. 28, 1909.

Application filed February 11, 1908. Serial N 0. 415,307.

To all whom it may concern:

Be it known that I, TVILLIAM J. Unnnun, of lVest Schuyler, in the county of llerkimer and State of New York, have invented certain new and useful Improvements in Milking-Machines; and I do hereby declare that the following is a full. clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same. reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form part of this specification.

The object of my present invention is to provide a portable, manually-operated milking machine, adapted for operation on two cows simullaneouslv. and which is simple in construction and efiicient in operation and well adapted to'fill the requirements of a practicable machine of this character.

'Figure 1 shows a vertical section of a machine of my present improved construction. Fig. 2 is a partial side elevation and partial sectional view of the teat cups employed in connection with the machine proper. Fig. 3 is a plan view of the set of teat cups with their appurtenances. Fig, 4 is a plan view of the machine. Fig. 5 is a plan view of the frame on which the machine is mounted, together with some details of construction.

Referring. to the reference figures in a more particular description, 10 indicates the frame bars 'on which the working parts of the machine are mounted, and which are supported at one end by posts 1111, and are provided at the other end with curved adjustable arms 12 supported on a truck having wheels 13. The posts 11 are carried up wardly, and, in connection with other frame bars, support a seat 1 1 for the operator and carry a handle 15 by means of which the.

machine may be handled and moved about, .one end earned or supported by the opera tor, while the other end is carried by the truck, the truck having the wheels 13.

Secured to and supported on the frame is the main milking receiving receptacle 16, which is a closed receptacle provide i with a tight cover 17 which may be removed to discharge the contents of the receptacle. Ar-

ranged in the top of the receptacle 16 and partially entering the same preferably, is the preliminary receiving chamber 18. This chamber is a closed chamber, except that it is provided with an opening or openings in the bottom into the receptacle 16 adapted to be closed by a valve 19. The valve 19 is mounted on a stem 20 and is held to closed position by a spring 21 arranged under the adjustable nut.- 22 on the upper end of the stem. One or more flexible tubes 23, )referably two, are provided connected-with the upper portion of the receiving chamber 18 and extending to sets of teat cups.

Secured on one side of the rt eeptacle 16 is. the'exhaust pump cylinder 24. The eylinder 24 contains thereciprocuting plunger or piston 25. The piston 25 is connecledbv a connecting rod :26 with the swinging end of a lever arm 27 secured on a rock shaft 28 mounted on the frame. A second rock shaft 29, also mounted on the frame. is provided and the two shafts 2S and .29 are connected together for simultaneous movenient by a pair of intcrmeshing gear sectors -30. ()n the outer end of one of the shafts. as 28, is secured a tread'le lever'31, while on the outer end of the other shaft is secured another treadle lever H is obvious that by alternately pressing on first one and then on the other of these treadle levers. the operator by means of his feet can reciprocate the plunger in the. cylinder EH. ln the head of the cyl nder 24 are provided outlet openings. which are closed against ingress of air by a valve 33, preferably in the nature of a flexible washer. The upper end of the cylinder 2-1- is connected with an opening in the upper end of the main receptacle 16 by a pipe 34-. The opening into the receptacle 16 is closed against air entering by a valve 35 in the nature of a flexible washer secured over the opening. Surrounding the opening" closed by the valve is a. valve chamber 36. This chamber has a valve seat with openings closed by a valve 37 held under tension by a spring 38. The spring 38 is confined between the valve 37 and the adjustable cap 39, the adjustment of the cap being effected by a screw 40 passing through the head of the valve chamber 36. ,The pipe 31 opens into the valve chamber 36'under the seat of the valve 37 and to the same space occupied by the valve 35. The portion of the chamber 30 above the valve 3'7 is placed in com- '1nunication with the top of the receiving operatedby a rod or connection at? extending from the'lever d6 to a position to be engaged by and operated by the lever arm 27. The

connection 47 will be mounted in bearings, as 48 and l9, to provide for a limited amount of longitudinal vertical movement.

At the-receptacle 16 the mill: pipes 23 may be provided with a stop cock 50, whereby they maybe shut ofi which stop cock is particularly useful when two or more pipes are provided, and the teat cups the pipes 23 will connect with a chamber in the head 51 which has four tubular branches, as 52, with which the teat cups are directly connected. The chamber 51 will preferably have an inlet opening controlled by a valve 53, held closed by'a spring and adapted to be the top do are defined by an ouin'ardl manually operated by means of the knob 55.

Eachoi? the tubular branches 52 will prefer-' ably be provided with a stop cock 56 and be given an upward direction at their ends for the more ready attachment of the teat cups. The teat cups consist of a generally holloiv cone-shaped body 6% continued at their lower ends ina pipe section 61 adapted to be attached to the pipe 52 and open at their upper ends to receive the teat. These teat cups of elastic runbcr and at intervals l with external. encircling ribs as 56,

.e ribs acting as a ht the up end oi the cup. The wa nail increa in st tional vie" in line on the outer side. and the inside, whereby the Walls l tivelythinncr a to the ribs and thick-- at the point substantially midway tween the ri.) Th construction of tea-t. cup is particularly etncieiit and well an: ted ciih the nut-chine herein descri ot-td. .e the l h of the teat -tsi n piece 62 is g irovided hav ingas to its lower end an internal groove the. bead on the upper and of'thc .t'eg;- .ar ocdy of he tea cup and being torn-led from pliable mater-i l, rubber, and having the same general form of walls as the regular body oi the teat cup.

he a achine mounted on the frame as de scribed may be readily brought by the operator and stationed between two anii'nals est vcan be lee held in stanchions in the stable in the usual manner. A few strokes by the operator of the treadles will exhaust .the air from the main receptacle 16 to an extentnecessaryto begin operations. As the piston 25 descends in its operation it draws air into the cylinder from the receptacle 16 through the open-:

ing closed by the valve 35, and through the pipe As the piston 25 ascends, the air is forced out through the openings closed by the valve 33., except as to a certain portion hereafter referred to. With each stroke of the piston, particularly when a complete up stroke of the piston is effected, the valve 15} is open and the chaniber ltl is exhausted into the main receptacle 16, so that there will be an equal degree of raretication in both. The teat cups may then be applied and the stop cocks 50 and 56 opened. The general. arrangement of the machine is such that the operatorwvill be conveniently located with referenceto two animals, so that he can apply and manage two sets of teat cups S1 With each down stroke of the piston the reeach upstroke of the piston a certain amount of air will be accumulated in the pipe 3": and passed through the opening closed by the valve 37 and passed into the receiving chamber 18, which will temporarily reduce the 'rarefication in this chamber to a certain exlent, as may be desired, considering the WOIlibeing; performed by the cups. amount at the reduction in the vacuum tension in he chanioer 18 will be regulated and. conoiled by the tension on the spring 38. At o up sir-eke oi the piston 25 the teat cups the teat cup connecons or pipe 43 into the chamber 18, as all any mill; taken into this chamber,

scharged into the receptacle 16 and nher 18 again brought to a degree of lion equal to' that existing in the main receptacle.

Tlhe. valve 19 is only opened at the limit at he upstroke of the piston, and the intro divticn of air into the chamber 18 from the 234i is prior to the opening of this so that there a pulsation incident to e "on of the degreoof suction at the at the will the. operator, air into the chamber of the teat cup head by opening the valve 55' manually. This will facilitate the removaliof inilh contained in the conn ions and p etliiii" the receiving chainh in order other I i.

be open and any air taken in he conclusion at the milking or at any ceptacle exhausted more or less. 'With tate the carrying of the teat cups on the, machine, a bow frame 70 is provided on the upper end of the main receptacle carrying hooks 71 upon which the teat cup head can be engaged 'when the teat cups are not in actual use.

It is evident that numerous changes and modifi -ations may be made in and from the construction described without departing from the spirit of my invention.

'hat I claim as new and desire to secure by Letters Patent is:

1. In a milking machine, the combination 'of a main closed receptacle, a closed rela tively small preliminary receiving chamber opening into the mam receptacle, a valve controlling the passage from the preliminary chamber into the 'main receptacle, means for exhaustingthe main receptacle, teat cups connected with the receiving chamber and means fo' periodically placmgthe preliminary chamber in counnuni aition with the main receptacle, substantially as set forth.

2. In a milking machine, the combination of -a main closed milk receiving receptacle, a closed relatively small prelinnnary chamber opening into the main receptacle, a valve controlling the passage from the prc liminary chamber into the main receptacle. means for exhausting the main receptacle, means for periodically placing the preliminary chamber in communication with the main receptacle. means for periodically re-'.

ducing the tension of apartial vacuum in the preliminary chamber, and teat cups connected with the preliminary receiving chamber. substantially as set forth.

3. In a milking machine the combination of a main closed receiving receptacle, a pump for exhausting said receptacle. a closed relatively small preliminary chamber arranged above and opening into the main receptacle. a valve controlling the passage from the preliminary chamber into the main receptacle. means operating in connection with the pump for controlling said valve, means for reducing the vacuum pressure 111 i i l l i tegral elastic ribs, the alls of the 01:15
